Abstract

This study aims to explain the effect of tofu waste as liquid organic fertilizer on the growth and production of tomato plants (Lycopersicum esculentum) and its use as a learning media in the form of posters. This research was conducted at the Green House Biology FKIP UNTAD from November 2020 to February 2021. The method used was an experimental method with a completely randomized design (CRD) one factorial experiment consisting of 4 levels of treatment (P0 = control, P1 = 200 ml, P2 = 400 ml, P3 = 600 ml) and 3 replications. Parameters observed in this study were plant height, number of leaves, number of branches, number of fruits, and stem diameter at 15 DAP, 30 DAP, 45 DAP, and 60 DAP. The calculated parameters were the number of fruit and fruit weight at 60 DAP. The results of this study showed that the best growth and production was P1 treatment with a dose of 200 ml of liquid organic fertilizer tofu waste. This can be seen in the analysis of variance for each parameter, namely plant height with Fhit 4.90 > Ftab 4.07, number of branches Fhit 8.14 > Ftab 4.07, number of leaves Fhit 7.13 > Ftab 4.07, stem diameter Fhit 12.92 > Ftab 4.07, number of fruit values Fhit 11.83 > Ftab 4.07, and the weight of the fruit is Fhit 11.36 > Ftab 4.07, then H0 is rejected and H1 is accepted. Thus, it can be concluded that liquid organic fertilizer from tofu waste can affect the growth and production of tomato plants with the best dose of 200 ml at 60 DAP. Based on the validation test and has been tested on students, the overall results of the study are very feasible to be used as learning media with an average percentage of 81.84%.

Abstract

This study aims to describe the impact of using the ChatGPT website in the learning process of Biology students at SMA Negeri 1 Torue. This study uses a qualitative method with a descriptive approach. The subjects in this study were students from SMA Negeri 1 Torue XI and XII, with the number of subjects taken as 10% of the total student population, with 32 students in grade XI and 30 students in grade XII. Data collection techniques involved using a questionnaire filled out by the students, with evaluations using a Likert scale. Observations at SMAN 1 Torue revealed that students have extensively used ChatGPT in the learning process during discussions, and the use of ChatGPT in the biology learning process has both positive and negative impacts. The results of this study indicate the impact of ChatGPT use on the cognitive aspect with an average total percentage of 59%, on the affective aspect with an average total percentage of 69%, and on the psychomotor aspect with an average total percentage of 41%. It can be concluded that there is an impact of using the ChatGPT website in the learning process of Biology students at SMA Negeri 1 Torue.

Abstract

This study aims to identify teachers' efforts in arousing students' interest in biology learning in public high schools in Dondo District. The study used a descriptive qualitative approach with research instruments in the form of observation sheets, questionnaires, and interview guidelines. Data collection techniques were carried out through observation, questionnaires, and interviews. Data were analyzed through the stages of data reduction, data presentation, and drawing conclusions, while the questionnaires were processed descriptively to identify trends in each indicator of teacher efforts. The results showed that teachers had made various efforts to arouse students' interest in learning, with the highest achievement in the indicator of creating a pleasant atmosphere, followed by giving praise and varied learning methods, and efforts to relate the material to everyday life. Meanwhile, the indicator with the lowest achievement was providing feedback that had not been given specifically to each student. This finding was reinforced by the results of interviews that showed that teachers tried to create interesting learning through a variety of methods, concrete examples, and positive interactions during learning. This study concludes that teachers' efforts to arouse students' interest in learning biology have been effective, but the provision of feedback and strengthening of more equitable learning collaboration needs to be improved.

Abstract

Learning motivation is a key element in achieving optimal learning outcomes. Observations at SMANOR Tadulako Palu revealed that the learning motivation of grade XI B students is still moderate and requires improvement. The purpose of this study was to evaluate the extent to which the implementation of problem-based learning and culturally responsive learning improves learning motivation. This study used a classroom action approach, conducted in two cycles through planning, implementation, observation, and reflection. The instrument used was a learning motivation questionnaire, and the data were analyzed descriptively. There was an increase in student learning motivation, as evidenced by the fact that in the pre-cycle phase, only five students were in the very high motivation category, while in the second cycle, this number increased to thirteen. The combined implementation of problem-based learning and culturally responsive learning has proven effective in increasing learning motivation by creating more contextual, engaging, and relevant learning that reflects students' cultural backgrounds.
